' SKATE.

SPECIFICATION forming part of Letters Patent No. 240,426, dated April19, 1881.

Application filed February 12, 1881. (No model.)

To all whom it may concern Beitknown that I, MOsES KINSEY, of Newark, inthe county of Essex and State of New Jersey, have invented a new anduseful Improvement in Skates, of which the following is a specification.

My invention relates to adjustable clampskates wherein a lever is madeto operate the sole and heel clamps by one action, imparting to bothclamps a backward longitudinal movement; and it consists in the order ofthe arrangement of the heel-clamp relatively to the heel-plate, in thearrangement of a presserbar to act on the front of the heel, in thepivotal arrangement of the lever, and in the combination to operate thesole-clamps.

Figure l is a plan, showing the lever closed against the side of theskate in the act of clamping. Fig. 2 is a plan with the lever partlyswung out. Fig. 3 is a side elevation with a heel clamped in position.Fig. 4 is an end view without a heel. The sole is designedly not shownin the drawings.

In my construction, A is a skate-runner, to which is attached the fixedheel-plate B, and above this plate, and sliding on it, is a heelclampplate, 0, provided with the spurs D, to catch into the rear portion ofthe heel E, and the studs F, having a flanged side to catch over theedge of plate B, holding it in a sliding position, together with thedouble-flange stud F, secured to the plate B, with the shank below theflanges sliding in the slot G in the.

plate (J. Other methods of making the sliding connection between thesetwo plates may be employed with the same effect, the one point, in thisrespect, bein gin the clamp-plate sliding on and above the heel-plate inthe backward movement in clamping, this heel-clamp not being attached tothe skate, but being made to slide above the heel-plate, and by a rearmovement in clamping adds greatly to the strength of the skate, as whenit is put on and tightened up there is no strain on the runner or backof clamp G to weaken them, as will be seen.

Connected with the front end of plate 0 is a screw-bolt, H, having ascrew-connection with the sole-clamps I, and is used to act upon theclamps in adjusting them to the size of a boot or shoe. The clamp-piecesI have the inclin ed slots K, in combination with the flanged studs L,secured to the foot-plate M, said footplatelyingabovetheclamp-plates.Theflangestud N, also secured to the foot-plate and lying between theclamp-plates, assists to keep them steady in their movements.

At the rear end and on top of the foot-plate M, by the pin 0, is pivotedthe lever P. At a short distance back, and diagonally from this pivot,is a pivot-pin, Q, uniting with the lever a presser-bar, R, having anupward curved form, as shown in Fig. 3, and made'to extend back to pressagainst the inside of the heel. The lower portion of the end T of thisbar has the stud U, adapting it to slide in the slot Gin the plate 0.

Now, it will be seen that to attach the skate to a boot the lever isthrown out laterally, as seen in Fig. 2, or farther than there shown,when the sole-clamps will be spread apart and the presser-bar be drawnforward, when the skate may be easily put in position on v the boot. Thelever is then turned in, approaching a parallel with the presser-bar,which bar is carried back by the action of the lever from therelation ofthe pivot-pins O and Q, as shown in Figs. 1 and '2. When the lever hasclosed in against the skate the pin Q has passed the center or pressureline of pin 0 and become a lock for the lever and presser-bar, as seenin Fig. 1; As the lever is turned in the presserbar strikes the front ofthe heel and presses it back, the clamp-plate O, on which it rests,sliding, as above shown, backward on the heel-plate. This movement ofplate 0 draws back with it the sole-clamps I, the outer ends of which,by the inclined slots K being drawn inward, clamp onto the sole andfirmly bind the skate to the boot.

B y this construction and operation the strain in clamping is almostentirely taken off from the skate-runner, as before stated, from theheel-clamp not being fixed to the runner, and also from the fact thatthe clamps both move in one directionbackward-in clamping, and leave nochance for strain, and yet the skate is perfectly clamped to the boot.

Some other form of operating the lever or of sliding back theheel-clamp, and with it the sole-clamps in one continuous action, may beemployed, and the same result be securedviz., of clamping the heel andsole by a backward movement of these clamps.

I claim 1. In a skate, the heel-clamp 0, provided with the spurs D andsliding on the top of the heel-plate B, and With the heel E of a boot orshoe carried backward in clamping by operating mechanism in front of theheel, in combination with the sole-clamps I, substantially as and forthe purpose specified.

2. In combination with the heel-clamp (J, constructed and operatingsubstantially as described, the sliding presser-bar R and lever P,substantially as and for the purpose set forth.

3. In combination with the heel-clamp G, constructed and operatingsubstantially as described, the level P, pivoted on a center line to therear end of the foot-plate M by the pin 0, and the presser-bar R by thepin Q, pivoted to the lever, so that when the skate is clamped on theboot 0r shoe the pin Q has passed the pressure-line of pin 0 and becomea locking device, substantially as set forth.

4. The backwardly-sliding heel-clamp G, with its spurs D, arranged aboveand sliding on the heel-plate B by means of the studs F and F, incombination with the sliding presserbar R, substantially as and for thepurpose specified.

5. The combination of the backwardly-sliding heel-clamp O, presser-barR, lever P, soleclamps I, and adjustable screw H, substantially as andfor the purpose-set forth.

MOSES KINSEY.
